Is it difficult to bond car touch screens? A RTV silicone solution makes it easy for you to handle!

With the rapid development of intelligent cockpit technology in automobiles, the touch screen of the vehicle’s central control has become the core of human-machine interaction. Whether it’s entertainment, navigation, air conditioning, or vehicle settings, a high-definition large screen carries more and more functions. However, the structural bonding technology behind the large screen is often overlooked. Today, we focus on a specific application point – the bonding problem between the screen film and aluminum frame of car touch screens, and bring a professional grade adhesive to solve such challenges: RTV SIPC 1822.

Adhesive bonding of car touch screen
1、 The challenge of bonding the structure of car touch screens
In the car display system, multi-layer composite structures such as touch glass, polarizing film, and conductive film need to be assembled onto aluminum alloy structural components through precision bonding. There are many technical challenges faced in this process:
Limited bonding width: Due to appearance and structural design, the bonding surface of the screen frame is often only about 3mm, and the shear strength and initial bonding force of the adhesive must be excellent.
High and low temperature impact: The temperature fluctuation of the car interior environment is large, ranging from minus 40 ℃ to 90 ℃ or even higher under sunlight exposure, requiring the colloid to have good thermal stability and low-temperature flexibility.
High durability requirements: The vehicle’s lifespan starts at 10 years, and the adhesive needs to withstand long-term comprehensive environmental tests such as UV, moisture, vibration, dust, etc.
Safety and Environmental Protection: The release material must be low volatile and non corrosive, especially not have a negative impact on materials such as PC and copper, and must comply with EU environmental regulations such as ROHS and REACH.
2、 Solution recommendation: RTV SIPC 1822
In response to the above challenges, we recommend using RTV SIPC 1822 neutral dealcoholized silicone adhesive sealant, designed specifically for harsh electronic application environments, suitable for bonding between aluminum frames and screen films, glass, PC, ABS and other materials.

Product Features Overview
Single component, room temperature curing, easy to apply, suitable for automated dispensing or manual glue application;
Low viscosity flowability design, easy to control the width and uniformity of the adhesive line;
Neutral dealcoholization curing system, releasing low volatility alcohols, non corrosive;
Excellent adhesion performance, suitable for aluminum PC、 Glass and other materials have good adhesion, and there are obvious residual adhesives in the damage test;
Excellent high and low temperature performance: After curing, it forms a flexible rubber body that can maintain stable mechanical and electrical properties between -60 ° C and 200 ° C;
Excellent aging resistance: resistant to UV, moisture, ozone, and pollutants, can be used outdoors for more than 20 years;
Excellent electrical insulation and anti corona capability, protecting precision electronic components from external interference.
The development of in car central control screens has put forward higher requirements for structural adhesives, especially in terms of weather resistance, reliability, and environmental friendliness. RTV SIPC 1822 not only has comprehensive performance and strong adhesion, but also helps customers improve assembly efficiency and product stability, making it an ideal choice for bonding mid to high end car touch screens.
